Featured: Hooded wrapcoat by Mara Hoffman

The appeal of the flat-felled seam is that it makes the joint stronger by running two lines of stitches through each piece of fabric, while simultaneously encapsulating the raw edges and preventing them from unraveling. This is the special seam that designers use to create your denim jeans. What’s more, it’s pretty simple once you get the concept. You can make it even easier by running an iron over the seam after you make each fold. Set it to a low heat so that you don’t scorch your fabric and try making a hooded wrap coat like this one from Mara Hoffman. Use a cozy double-sided winter coating and skip the lining.

You will need:

  • 3 1/4 yds. of fashion fabric, 54″ wide
  • 2 yds. of stay tape. 5/8″ wide
  • coordinating thread

PATTERN

Add a 3-1/2″ hem allowance to the body pattern pieces and appropriate seam allowances for desired size of flat-felled seams (I used 3/4″ for 3/8″ flat-felled). All other seaming can be 1/2″ seam allowance.

THE FLAT-FELLED SEAM

To begin, lay one piece of fabric on top of the other.  The bottom piece of fabric should extend beyond the upper piece by the width of the seam (the seam-to-be, that is). Sew a line of stitching in from the edge of the top piece by the width of the seam.

Flip the bottom piece out from underneath so that both are lying flat on the table and the extra flap sticks up in the air. Fold the longer flap down over the short one and then fold both of them down flat, as shown. Sew a line of stitches to hold down the flap. When you sew this second row of stitches, be sure to gently pull the two pieces of fabric taut and press the overlap flat as you feed it through the sewing machine. This will result in a cleaner and stronger seam.
